Im trying to figure out how to set my white balance using a white or grey card, I go to FN then white balance menu then i go to manuel then I click on the right arrow then I take the picture, but it doesnt set my white balance correctly? not sure how it work

Ok franky i think ive found your answer. It is instructions for the K10D but It should be the same menu system. If im understanding you correctly you want to use a white or gray card to adjust your wb manually depending on the environment you are in right? Here are the instructions on how to do so....
